I wonder if keys were generated by some deterministic wallet first, and then truncated to N bits. Because in that case, it could be possible to recover the master key, and then sweep coins from all of them, while it would not mean that ECDSA is broken (because HD keys could be non-hardened).
Interesting puzzle, i thought this maybe to, checked at pattern between binary values, decimal values, floor values. Just can find anything
I updated an excel sheet with allot more data of each puzzle I added, but I'm stumped
Since this range is just so huge, I think a random generator would maybe work best to try and find the needle.
I attached below my python script trying the next puzzle randomly if someone might benefit to
